1. A method of controlling Discontinuous Reception (DRX) reference parameter or DRX parameter configuration proposal reporting, comprising: transmitting, by a network side device, indication information to a terminal which indicates whether the terminal is permitted to report a DRX reference parameter or a DRX parameter configuration proposal, wherein the DRX reference parameter is a DRX parameter to be configured by the network side device, desired by the terminal, the DRX parameter configuration proposal is a power consumption state desired by the terminal, and wherein: the indication information is used to indicate the terminal: to report the DRX reference parameter or the DRX parameter configuration proposal when the terminal receives the indication information for permitting reporting of the DRX reference parameter or the DRX parameter configuration proposal; and not to report the DRX reference parameter or the DRX parameter configuration proposal when the terminal receives the indication information for not permitting reporting of the DRX reference parameter or the DRX parameter configuration proposal.
Wireless communication power management. This invention addresses the control of Discontinuous Reception (DRX) parameter configuration and reporting in wireless networks to optimize terminal power consumption. DRX allows a terminal to periodically wake up to check for incoming data, saving power when idle. The method involves a network side device transmitting indication information to a terminal. This indication informs the terminal whether it is allowed to propose or report its desired DRX parameters or a DRX parameter configuration proposal. A DRX reference parameter is defined as a DRX parameter that the terminal desires to be configured by the network. A DRX parameter configuration proposal represents a power consumption state that the terminal desires. Specifically, the indication information instructs the terminal to report its DRX reference parameter or DRX parameter configuration proposal if the indication permits such reporting. Conversely, if the indication informs the terminal not to permit reporting, the terminal refrains from sending its DRX reference parameter or DRX parameter configuration proposal. This mechanism allows the network to manage when and if terminals can suggest their power saving preferences.
2. The method according to claim 1 , wherein transmitting, by the network side device, indication information to the terminal which indicates whether the terminal is permitted to report the DRX reference parameter or the DRX parameter configuration proposal comprises: the network side device transmits indication information to the terminal for permitting the reporting of DRX reference parameter or the DRX parameter configuration proposal when the network side device configures a DRX parameter for the terminal; or the network side device transmits indication information to the terminal for not permitting the reporting of DRX reference parameter or DRX parameter configuration proposal after the network side device receives DRX reference parameter or DRX parameter configuration proposal reported from the terminal; or the network side device transmits indication information to the terminal for permitting the reporting of DRX reference parameter or the DRX parameter configuration proposal, wherein the indication information indicates the terminal to report the DRX reference parameter after receiving the DRX parameter configured by the network side device for the terminal; or the network side device transmits indication information to the terminal for permitting the reporting of the DRX reference parameter or the DRX parameter configuration proposal, wherein the indication information is used to indicate the terminal to report the DRX reference parameter or the DRX parameter configuration proposal when the terminal switches its power consumption state.
In wireless communication systems, Discontinuous Reception (DRX) is used to reduce terminal power consumption by defining active and inactive periods. However, existing methods lack flexibility in allowing terminals to propose or report DRX parameters, leading to suboptimal power efficiency. This invention addresses this by enabling a network side device to dynamically control whether a terminal can report DRX reference parameters or propose DRX parameter configurations. The network transmits indication information to the terminal under specific conditions. When the network configures DRX parameters for the terminal, it may permit reporting of DRX reference parameters or proposals. Alternatively, after receiving a DRX reference parameter or proposal from the terminal, the network may prohibit further reporting. The network can also permit reporting only after the terminal receives configured DRX parameters or when the terminal switches its power consumption state. This dynamic control ensures efficient power management while maintaining network flexibility. The invention improves DRX configuration adaptability, allowing terminals to contribute to parameter optimization under network supervision.
3. The method according to claim 2 , wherein when the network side device transmits indication information to the terminal for permitting the reporting of the DRX reference parameter or the DRX parameter configuration proposal, the method further comprises: receiving, by the network side device, the DRX reference parameter or the DRX parameter configuration proposal reported by the terminal; and wherein the DRX parameter configuration proposal comprises: switch from a DRX parameter configuration in a default state to a DRX parameter configuration in a more power saving state, or switch from the DRX parameter configuration in the more power saving state to the DRX parameter configuration in the default state, or switch from the DRX parameter configuration in the default state to a DRX parameter configuration with a shorter configuration cycle, or switch from the DRX parameter configuration with the shorter configuration cycle to the DRX parameter configuration in the default state.
In wireless communication systems, power efficiency is critical for terminal devices to extend battery life. Discontinuous reception (DRX) mechanisms allow terminals to periodically enter low-power states, reducing energy consumption while maintaining connectivity. However, existing DRX configurations may not optimize power savings based on varying network conditions or terminal requirements. This invention addresses the need for dynamic DRX parameter adjustments by enabling a network-side device to request and receive DRX-related information from a terminal. The terminal can report a DRX reference parameter or propose a DRX parameter configuration change. The proposed changes include switching between a default DRX configuration and a more power-saving state, or adjusting the DRX cycle length. The network-side device evaluates these proposals and may implement them to optimize power efficiency. This approach allows for adaptive DRX management, balancing power savings and network responsiveness based on real-time conditions. The invention improves terminal battery life without compromising communication reliability.

The invention provides a method where a network side device transmits indication information to a UE. The indication information can be carried either in a broadcast message or via dedicated signaling. The dedicated signaling includes Radio Resource Control (RRC) layer signaling or Media Access Control (MAC) layer signaling. Broadcast messages allow the network to send the same information to multiple UEs simultaneously, while dedicated signaling enables targeted communication with specific UEs. RRC signaling is used for higher-layer control, such as configuration updates, while MAC layer signaling is used for lower-layer control, such as resource allocation. This approach ensures that the network can efficiently convey critical information to UEs based on their specific needs, improving overall system performance and resource utilization. The method supports both one-way broadcast and two-way dedicated signaling, providing flexibility in how the network communicates with UEs.
6. The method according to claim 5 , wherein when the indication information is carried in the MAC layer signalling by the network side device, the MAC layer signalling is represented by a preset Logic Control Identity (LCID); or when the indication information is carried in the RRC layer signalling by the network side device, the indication information is carried in an RRC reconfiguration message.
This invention relates to wireless communication systems, specifically methods for transmitting indication information from a network device to a user equipment (UE) to control data transmission.

This invention relates to wireless communication systems, specifically methods for optimizing power consumption in terminals through Discontinuous Reception (DRX) configurations. The problem addressed is the inefficiency in power management when terminals lack the ability to propose or report preferred DRX parameters to network devices, leading to suboptimal battery usage. The method involves a terminal determining whether it meets a triggering condition to report DRX-related information. The triggering condition is satisfied when the terminal receives permission from a network device to report either a DRX reference parameter or a DRX parameter configuration proposal. The DRX reference parameter is a specific DRX parameter that the terminal desires the network to configure, while the DRX parameter configuration proposal represents a power consumption state preferred by the terminal. Upon meeting the triggering condition, the terminal transmits this information to the network device, enabling dynamic adjustment of DRX settings to better align with the terminal's power efficiency needs. This approach enhances energy efficiency by allowing terminals to influence their DRX configurations based on real-time requirements.

The method according to claim 7 , wherein the DRX parameter configuration proposal comprises: switch from a DRX parameter configuration in a default state to a DRX parameter configuration in a more power saving state, or switch from the DRX parameter configuration in the more power saving state to the DRX parameter configuration in the default state, or switch from the DRX parameter configuration in the default state to a DRX parameter configuration with a shorter configuration cycle, or switch from the DRX parameter configuration with the shorter configuration cycle to the DRX parameter configuration in the default state.
In wireless communication systems, power efficiency is critical for user devices to extend battery life. Discontinuous reception (DRX) mechanisms allow devices to periodically enter low-power states to conserve energy while maintaining connectivity. However, existing DRX configurations may not dynamically adapt to varying network conditions or device activity levels, leading to suboptimal power savings or degraded performance. This invention addresses the need for adaptive DRX parameter adjustments by proposing a method to dynamically switch between different DRX configurations based on operational requirements. The method involves transitioning between a default DRX state and a more power-saving state, or between the default state and a configuration with a shorter DRX cycle. The transitions can occur in either direction, allowing the system to balance power efficiency and responsiveness. For example, when network activity is low, the device may switch to a more power-saving DRX configuration to reduce energy consumption. Conversely, when higher responsiveness is needed, the device may revert to the default or shorter-cycle configuration to ensure timely data reception. This adaptive approach optimizes power usage while maintaining communication reliability.

This ensures that the terminal operates with optimized DRX settings tailored to its network environment, improving energy efficiency without compromising communication reliability. The method may also include dynamically adjusting these parameters based on network conditions or terminal activity to further enhance performance. By using a default DRX configuration, the terminal can quickly adapt to network changes or transitions between different network states, reducing latency and power consumption. This approach is particularly useful in scenarios where the terminal frequently switches between active and idle states, such as in mobile devices operating in heterogeneous networks. The invention aims to provide a flexible and efficient way to manage DRX parameters, ensuring optimal power usage while maintaining seamless connectivity.

Physical layer signaling offers the fastest but most resource-intensive option, typically used for urgent adjustments. By supporting multiple signaling methods, the terminal ensures flexibility in DRX parameter management, allowing the network to choose the most efficient approach based on current conditions. This adaptability enhances power efficiency and reduces unnecessary signaling, improving overall system performance. The invention is particularly relevant in 5G and beyond networks, where dynamic resource allocation and low-latency communication are critical.
